1 Simplified Operations for TM-3100 Series Digital Tachometer The TM-3100 series Digital Tachometers has the most fundamental function in rotational measurement of four standard models (rotation speed display, BCD output, analog output, or comparator output) and can be customized by adding optional cards in order to match your application. TM-3110 TM-3120 TM-3130 TM-3140 Display only With BCD open collector output With analog output With comparator output This section describes the operation procedures for the above four standard models. For the measurement and calculation functions of the optional card TM-0350 (RS-232C/GATE), please refer to the complete instruction manual. Basic Concept The TM-3100 series has the following three basic concepts: Measures the frequency of the input signal and displays the results in various measurement items after calculation. By simply setting the unit of measurement item, the results are converted and automatically displayed. Two measurement modes, such as NORMAL (normal continuous measurement) and SS (measurement between start and stop timings), are available. If the system is to be used as a replacement of the TM-2100, TM-800, or TM-8000 series or as a general tachometer or speedometer, select the NORMAL (normal continuous measurement) mode. The SS measurement mode and optional TM-0350 (RS-232C/GATE card) are newly equipped functions. Measurement Mode (MEAS MODE) Two measurement modes of NORMAL and SS are available. 1. NORMAL mode In the NORMAL mode, measurement is continued with a specified update time interval (e.g.: 1 second) and displayed. The NORMAL mode is used for general rotation speed or line speed measurements. This mode is compatible with old models (TM-800/8000 and TM-2100 series) because the measurement method is the same

2 2. SS mode (Measurement between start and stop timing) The SS mode is used to measure the AVERAGE, MAX (maximum), and MIN (minimum) values in a measurement section. Depending on what condition of the start and stop measurement section is specified, either MANUAL or AUTO measurement is used. In the MANUAL mode, the measurement section is determined by the START and STOP switches (or by the external input of the TM-0350). In the AUTO mode, the measurement section is determined by the setup of the start condition and measurement time. The details are provided in later sections. MANUAL Measurement value (rotation speed, etc.) Start input (Key switch, external control terminal or RS-232C) Stop input SS measurement stopped SS measurement in progress (average, maximum, and minimum values) Time SS measurement stopped AUTO Measurement value (rotation speed, etc.) Start input (Key switch, external control terminal, or RS-232C) SS measurement start value SS measurement stop value (time) SS measurement stopped Ready for SS measurement SS measurement in progress (average, maximum, and minimum values) SS measurement stopped Time Caution: Be careful when you use the SS mode as the measurement mode, Normal or SS will affect the operation of the comparator and BCD output functions

3 Measurement Item and Calculation Formula The TM-3100 series tachometer measures the period (frequency) of the input signal. Process the calculation by using the measurement frequency with the value which sets at the measurement item as the coefficient value, and display with the specified unit. For example, when sets the number of pulses per rotation or the diameter of the roller, the rotation speed (r/min) or the circumferential speed (m/min) can be displayed. The measurement items and the calculation formula (parameters) are listed in the following table. Note that the unit conversion coefficient (K) is automatically processed according to the setup of the measurement unit. * K: Unit conversion coefficient (fixed coefficient for converting the display unit, e.g., seconds to minutes) Measurement Display Unit Calculation Formula Item ROTATION (Rotation Speed) r/s, r/min, r/h ROTATION = Measurement Frequency PULSE FACTOR K L.SPEED (Circumferential Speed) VELOCITY (Moving Speed) PERIOD (Period) TIMES (Number of Times) FREQ (Frequency) FLOW (Flow Rate) P.TIME (Passing Time) OTHER (Engineering Unit) mm/s, m/s, mm/min, L.SPEED = Measurement Frequency PULSE DIAMETER π m/min FACTOR K mm/s, m/s, mm/min, VELOCITY = Measurement Frequency PULSE DISTANCE FACTOR m/min, km/min, mm/h, K m/h, km/h s, min PERIOD = 1 Measurement Frequency K 1/s, 1/min, 1/h TIMES = Measurement Frequency FACTOR K Hz, khz FREQ = Measurement Frequency FACTOR K ml/s, ml/min, ml/h, l/s, l/min, l/h FLOW = Measurement Frequency FACTOR K s, min P.TIME = PROCESS LENGTH L.SPEED FACTOR K L.SPEED = Measurement Frequency PULSE DIAMETER π EU/s, EU/min, EU/h OTHER = Measurement Frequency FACTOR K Example use of FACTOR Assume that a decelerator is used and the rotation detector is fixed to the input axis. If it is desired to display the rotation speed of the output axis, setup the gear deceleration ratio as FACTOR. Generally, FACTOR is setup as

12 Analog Output For analog output, the TM-0330 (analog output card) is required. Note that TM-0330 card is incorporated to the TM Either voltage output or current output is selected for the analog output. The display value that corresponds to the full scale voltage (or current) can be setup freely.

Note that the TM-0340 card is incorporated to the TM Three comparator outputs, COM 1, 2, and 3, are available. The mode is to be selected from AUTO (automatic recovery mode), MAINTENANCE (output hold mode), and PULSE (single-shot output mode). Either UPPER or LOWER judgment is made with the measurement value, compared with the setup value. It is also possible to setup the system to output the status of ERROR (operation error) or OK (normal operation). Note that the comparator output in the case of SS measurement will be synchronized with the measurement start/stop timing.

Comparator output specification UPPER setup LOWER setup OK setup ERROR setup Output type Measurement mode COMP delay function Reset function 6-digit setup (Relay is ON when; UPPER display value) 6-digit setup (Relay is ON when; LOWER > display value) The relay is ON when both UPPER and LOWER output contacts are open. The relay is ON when any error occur other than the RS communication error. Single make contact output Three outputs of COMP 1, COMP 2, and COMP 3 (with one UPPER, LOWER, OK, or ERROR output) Selection of the comparator operation mode Automatic recover mode Output hold mode Shot output mode The comparator automatically recovers when the rotation speed is within the specified range. Comparator hysteresis Adds a hysteresis to the comparator reference value for recovery. The output status is held even after the rotation speed is returned to the specified range. OFF (factory default output), 10 to 2000 ms in 10 ms increments The comparator output is held for a period of time when the rotation speed is within the specified range. 0 to 1000 ms in 50 ms increments The comparator produces the output only when the reference value is exceeded continuously for a specified period. Returns to the comparator hold mode

15 Maximum rating Output interface Output update time DC: 30 V/1 A AC: 250 V/1 A Terminal block About 10 ms Comparator output specification 1. Comparator automatic recover mode: AUTO The comparator will continuously output the comparison result for the measurement value. For the judgment, a hysteresis can be setup to provide the difference between the rising edge (when the comparator turns ON) and trailing edge (when the comparator turns OFF). The following example shows the case when COMP 1 is setup to UPPER and COMP 2 is setup to LOWER comparators, with the rotation speed of 1000 r/min, and the hysteresis of 10%. Lights off (contact OFF) UP lights on (contact ON) Lights off (contact OFF) LO lights on (contact ON) Hysteresis Lights off (contact OFF) LO lights on (contact ON) Lights off (contact OFF) 2. Comparator hold mode: MAINTENANCE Once the comparison condition is satisfied, the result of comparator output will be held. When the RESET switch is pressed or an external reset signal is applied with optional TM-0350, the comparator output will be reset. Note that in the case of SS measurement, the reset function can be used only after the measurement is stopped. Lights off (contact OFF) UP lights on (contact ON) LO lights on (contact ON)

16 3. Comparator pulse output mode: PULSE When the comparison condition is satisfied, a single-shot output is operated within the setup period of time. For example, when the output pulse time (SHOT PULSE WIDTH) is setup to 50 ms, the system operates as shown in the following figure. Lights off (contact OFF) UP lights on (contact ON) Lights off (contact OFF) LO lights on (contact ON) Lights off (contact OFF) 4. Comparator output delay: COMP DELAY The comparator output turns on when the comparison condition is continuously satisfied for a period of time. This delay can be specified in any comparator mode. By using the comparator output delay function, a stable operation can be expected. For example, when the comparator output delay (COMP DELAY) is set to 50 ms, the comparator output will be turned on after the input level exceeds the UPPER reference level, while the output is held for the 50 ms period. Lights off (contact OFF) UP lights on (contact ON) Lights off (contact OFF) After 50 ms has passed 5. Comparator normal: OK Comparator error: ERROR Besides the UPPER and LOWER comparator setups, OK and ERROR setup is available. When OK is selected, it outputs when the system is operating normally. Conversely, when ERROR is selected, it outputs when the system is operating abnormally due to improper input signal or setup conditions. Comparator normal: OK When the system is normally operating, the contact is turned ON. When either one of other two comparators is operated, the contact is turned OFF (excluding the case ERROR is set). Comparator error: ERROR The contact will be turned ON when an error occurs (excluding the RS communication errors)

17 SS (start and stop) Measurement Either MANUAL or AUTO measurement mode can be used. In either mode, a single measurement is completed from the start to stop. When repeating the measurement, it is to be started again. 1. SS-MANUAL mode In the SS-Manual mode measurement, the average and other values are measured in the interval from the point when the START switch is pressed until the STOP switch is pressed. Measurement value (rotation speed, etc.) Start input (Key switch, external control terminal, or RS-232C) Stop input SS measurement stopped SS measurement in progress (average, maximum, and minimum values) Time SS measurement stopped 2. SS-AUTO mode In the SS-Auto mode, pressing the START switch sets the system ready for measurement. The measurement starts when the setup start condition is satisfied and stops when the setup stop condition is satisfied. Then, measures in the interval between the start and stop times. Example: When the condition is; START at 2000 r/min and STOP after 10 seconds If the START switch is pressed at the rotation speed of 1000 r/min, the measurement will start when it reaches 2000 r/min after gradual acceleration. Then, the average, maximum, and minimum values are measured in the passing intervals of 10 seconds. As another example, if the START switch is pressed at the rotation speed of 2500 r/min and the rotation speed is decreased to 2000 r/min, the measurement will be started at this point. Please be careful about the rotation speed when you press the START switch. The measurement value will be displayed on the sub display. Measurement value (rotation speed, etc.) Start input (Key switch, external control input, or RS-232C) SS measurement start value SS measurement stop value (time) 10 seconds SS measurement stopped Ready for SS measurement SS measurement in progress (average, maximum, and minimum values) SS measurement stopped Time

18 Main display and sub display When DISPLAY - 2 LINE is selected in the setup mode, the main display shows the NORMAL measurement value and the sub display shows either the average, maximum, or minimum value of the SS measurement according to the selected value. Examples of the main display in a single line mode and the main/sub display in the two line mode are shown as follows. Main Display of TM-3140 (with the comparator function) (1 LINE display mode) The display of instantaneous rotation speed is updated every 1 second. Main and Sub Displays of TM-3110 (display only) (2 LINE display mode) SS: Indicates while measuring the maximum value. MAX: Display of maximum value in the measurement section which updates every 1 second

19 Function Board The rear card slots A to D are assigned to specific boards: slot A for the comparator, slot B for BCD or RS-232C/GATE, slot C for analog output, and slot D for the input board. For the TM-3110 (display only), TM-3120 (open collector BCD output), TM-3130 (analog output), and TM-3140 (comparator output), the specific function cards are already mounted in the corresponding rear slots. Any vacant slot can be used for an additional function. For example, you can add TM-0340 comparator to a TM-3130 system. If it is desired to implement an additional function after the unit has been delivered, the unit must be returned to the supplier Label on lateral side Rear panel Optional unit DC POWER (12 to 24 VDC) Optional unit Instead of the BCD board, an RS-232C/GATE board can be assigned
